The fate of hundreds of undocumented children taken from parents remains unclear a day after President Donald Trump moved to roll back his policy.
He ordered that the children be held with their parents, who are jailed on criminal charges of crossing the border illegally.
But under US law, migrant children cannot be detained more than 20 days by immigration officials.
US officials have expressed mixed messages about what happens next.
At least 2,300 children have been separated from their mothers and fathers after crossing the border illegally since May 5.
While the adults are held in custody pending court appearances, the children are being sent to holding cells, converted warehouses and desert tents.
